Kinetic modeling of polyphenylene sulfide polymerization reaction based on Monte Carlo method

Based on the polymerization mechanism and process analysis of polyphenylene sulfide (PPS) and reasonable assumptions, a kinetic model of PPS polymerization based on Monte Carlo method was proposed. The fitting regression of the model parameters was performed through literature data, and the results show that the calculated value based on the kinetic model is in good agreement with the corresponding experimental data, and the extrapolation prediction based on the model is consistent with experiments, with the deviation less than 2%. The effect of the reactants ratio on the polymerization reaction was calculated based on kinetic model, and the results is in accordance with the literature value. Finally, by establishing the reactor model of industrial PPS polymerization, the industrial production process was simulated, and the results show that the tanks-in-series mode should be adopted for this process. The relevant results in this work will provide theoretical basis to the kinetic modeling of PPS polymerization reaction and the design and optimization of industrial PPS production.
